Operation

INTERFACES

In most cases no adjustments are necessary to obtain a good quality picture on the display; however, dip-switches located on the front panel should be set for certain types of input and output signals. The factory default settings are shown below in Table 7. The VA6822 will operate successfully as long as cables are attached properly and all technical specifications of input and operating environment are maintained.

Table 7. Dip-switch default settings

7.1 H&V OUTPUT SWITCH

This dip-switch controls the type of sync signal that is present on the HSYNC connector. If the H&V output dip-switch is in the OFF position, then the composite sync signal is present on the HSYNC connector when the input in RGBS or RGBHV format. If the H&V output dip-switch is in the ON position, then the horizontal sync signal is present on the HSYNC connector when the input is in RGBS or RGBHV format.

7.2 H&V ALIGN SWITCH

By default the H & V ALIGN dip-switch is in the OFF position, so Horizontal and Vertical SYNC signals are independent. By turning this dip-switch to the ON position, the pulse of both HSYNC & VSYNC signals start at the same point for the benefits of some LCD projectors.

7.3 OPTION SWITCH

By default, this dip-switch is in the OFF position. By putting it in the ON position, the duration of Vertical SYNC of the signal is reduced to 10ms. This allows stability of the signal on a long run cable. It is not recommended to use the H&V ALIGN feature when the Option dip-switch is ON.

7.4 SYNC ON GREEN SWITCH

Often systems that use large matrix switchers are designed to switch signals in RGsB format. This is done to reduce the cost of the switcher and cable. In these types of systems, the ability of the VA6822 to output Sync on Green can be very helpful. It is important to note that the VA6822 will not separate the Sync signal from the Green video signal if the input signal is RGsB. When the Sync on Green dip-switch is in the ON position; the VA6822 will combine a composite sync of -0.3V amplitude to the green video signal to provide RGsB output if the input signal is in RGBS or RGBHV format from the source. When the Sync on Green dip-switch is in the OFF position, the unit will provide all RGsB, RGBS or RGBHV signals at the output connectors in the same format as the input.

7.5 ID BIT SWITCH

Some computers on the market, especially laptop computers, require the presence of a local monitor to correctly output video. The ID Bit switch, when turned ON, will connect Pin 4 to ground. This enables the interface to imitate a local monitor if one is not being used in the system. When the ID Bit switch is in the OFF position, the ID Bit of pin 4 is passed through to the local monitor output.

7.6 NOT USED

This dip-switch is not used for any settings at this time.
